A conronA'rIoNo'r wrsconsm CONTAINER Application filed November lates to a composite fabric formed of paper or the like.

' An object of my invention is to provide such a fabric which will comprise a soft mat adapted to contact with the fragile article to be wrapped, the said soft mat being backed '10 with a tough but flexible sheet, thisbacking sheet being suificiently tough to resist tearing to a high degree and atthe same time flexible enough to conform roughly to the shape of the wrapped article.

A further object is. to provide such a composite fabric which will include between the soft mat and the flexible sheet a relatively stifi' but expansible sheet, which serves to stiffen the composite fabric.

Still another object is to provide such a composite fabric which will be formed of inexpensive material, su ch as paper or the like. Another object is to provide an improved container, formed of the fabric above referred to, which is especially suitable for packing fragile articlesf Various other objects and advantages will appear' as the description proceeds.

Referring now to the drawings forming part of this specification Fig. 1 is a plan view of ,a container representing a preferred embodiment of my invention, with parts'of the layers brokerfaway to show the composition thereof.

Fig. 2 is a sectional view taken on the line 22 of Figure 1.

Fig. 3 is an open end view of the container in open position, and

Fig. 4 is a perspective view of a composite fabric sheet embodying my invention.

1 According to the particular embodiment herein shown, 10 represents a mat or p'ad formed of a plurality of sheets of very thin crepe paper, any desired number of sheets being used, in this case, five sheets. Obviopsly, any desired number of sheets may be used, of various grades and qualities of tissue or crepe paper. Adjacent and preferably secured to the mat 10, by glue or other suitable adhesive, is an interlining 12 of plain 5, 1930. Serial No. 493,592. \I

smooth paper, which may be archment pa.- per, kraft paper, or the like. t will be noted that in the example shown, the pad 10 and stiffening sheet 12 are corrugated as a unit, the object of such unit corrugation being to increase stiflfness in one direction. Disposed outside thestiflening'sheet 12 and in the presvent instance preferably secured thereto byv a light coating of glue or other suitable adhesive is a sheet 13. This sheet is preferably kraft paper which has been subjected to a- -creping operation. This paper is of relatively light weight but is extremely tough i. e., resistant to tearing, and by reason of being crinkled may be'stretched or elongated in a direction transverse to the crinkles. It will be noted that the sheet 13 isapplied so that the crinkles. lie substantially parallel to the corrugations of the pad 10 and stifiening sheet 12. 1

The composite fabric above described may -.be used in any-desired manner for packing fragile articles. The pad 10 is preferably disposed in immediate contact with the fragile article. The stifl'ening sheets aid in supporting the pad and protecting it from tearing" and also are of value in absorbing shocks. Both the pad and the stiflening sheet, by reason of being corrugated, are expansible and also are of increased resiliency as shock absorbers. The sheet 13 is also of great value in that it is extremely resistant to tearing and, is also extremely flexible adapting itself to any desired shape in the wrapping of an article and is expansible in the same directions as the pad and stiffening sheets i A preferred application of my invention is in the formof a container as shown in Figures 1 to 3. This container-may be formed by applying together two composite sheets of the type shown in Figure 4 in such manner that the pads 10 lie adjacent each other. The pads preferably dovetail, for economy of space in packing and to prevent crushing the corrugations. The two layers are cut into portions 15 of the desired size and shape.

j acent one end thereof so as to form a closed bottom for the container, the opposite end being unstapled in order that an opening may be formed between the similar portions of the container for the insertion of the article 18 which is to be packed. A staple 16 is also applied to each side of the container adjacent the open end, and another pair of staples 17 is applied and spaced further from the edges than the staples 16, also being spaced a short distance from the staples 16. In order to open the container for use, it being usually dispensed in its fiat or unopened condition as shown in Figure 2, the edges adjacent the open end may be grasped with the fingers and the portions separated along the skilled in the art. Hence, I do not wish to be specified, or uses mentioned except asset forth in the appended claims, which are to be interpreted as broadly as the state of the artpermits. f

I claim as my invention:

1. As a new article of manufacture, a container comprising a pair of layers of relativ'ely soft material disposed adjacent each other, and a pair of outside sheets of rela:

t-ively tough but flexible material, and means securing said layers-and sheets adjacent opposite edges thereof.

2; As a new article of manufacture, a container comprising a" pair of mats of tissue paper or the like, said mats being corrugated as a unit, and a pair of outside sheets of relatlvely tough but flexible paper, and means securing said mats and sheets adjacent opposite edges thereof.

3. As a new article'of manufacture, a container comprising a pair of relatively soft mats disposed adjacent each other, a pair of outside sheetsformed'of relatively tough but flexible material, and a pair of stiffening sheets interposed between said mats and said outside sheets, and means securing said'mats and sheets adjacent opposite edges thereof.

4. As a new article of manufacture, a container comprising a pair of mats formed of tissue paper or the like, a pairof outside sheets formed of relatively tough but flexible material, and a pair of stiffening sheets interposed between said mats and said outside sheets, said mats and said stiffening sheets being corrugated as a unit, and means scour-- in-g said mats and sheets adjacent opposite edges thereof.

sheets, limited to the SPQClfiC'fOIIIl shown, materials tainer comprising a pair of mats formed of ible and expansible paper, and a pair of stiffening paper sheets interposed between said mats and said outside sheets, said mats and said stiffening sheets being corrugated as a unit, and means securing said mats and sheets adjacent opposite edges thereof.

6. As a new article of manufacture, a container comprising a pair of relatively soft mats disposed adjacent each other, a pair of outside sheets formed of relatively tough but flexible material, and apair of stiffening sheets interposed between said mats and said outside sheets, adhesive means securing said stiffening sheets to said outside sheets, and means securing said mats and sheets ad acent opposite edges thereof.

7 As a new article of'manufacture, a container comprising a pair of mats formed of tissue paper or the like, a pair of outside sheets formed of relatively tough but flexible material, and a pair of stiffening sheets interposed between said mats and said outside said mats and said stiffening sheets being corrugated as a unit, adhesive means securing said stiffening sheets to said outside sheets, and means securing said mats and sheets adjacent opposite edges thereof.

8. As a new article of manufacture, a container comprising a pairof mats-formed of tissue paper or the like, a pair of outside sheets formed of relatively tough but flexible paper, and a pair of paper stiffening sheets interposed between said mats and said outside sheets, said mats and said stiffening sheets being corrugated as a unit, adhesive means securing said stifieningsheets to said outsi de sheets, and means securing said mats and'sheets adjacent opposite edges thereof.
